Randomize
for a wavefunction psi the method Randomize() will change all prefactors to random numbers. Real functions stay real, complex stay complex. Randomize does not add determinants to the basis.
Example
We can define the following function: $$ |\psi\rangle = \left(\frac{1}{\sqrt{4}} a^{\dagger}_0 a^{\dagger}_1 + \frac{1}{\sqrt{4}} a^{\dagger}_0 a^{\dagger}_2 + (1+I)\frac{1}{\sqrt{4}} a^{\dagger}_1 a^{\dagger}_2 \right)|0\rangle. $$ Randomization will turn $\psi$ into $$ |\psi\rangle = \left(\alpha a^{\dagger}_0 a^{\dagger}_1 + \beta a^{\dagger}_0 a^{\dagger}_2 + \gamma a^{\dagger}_1 a^{\dagger}_2 \right)|0\rangle. $$ with $\alpha$, $\beta$, and $\gamma$ random complex numbers.
